I put 4 years into him.. I've built a family with him.. i stayed by his bedaide for months and took care of him after a spinal cord injurt and a stroke.. we were looking at our first apartment together.. and today I found 3 sex/hook up apps downloaded on his phone and one of those has a profile set up because it's the only free one.. he's making this out to be no big deal and won't even talk to me about it. I've been sitting in our room crying for almost an hour and all he had to say was he didn't do anything wrong because he didn't do anything. He didn't message any of the girls or actually cheat on me so he thinks he didn't do anything wrong.. I've been sitting here trying to get the nerve to walk out the door.. but I cant.. I'm so stupid...
